Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens. See “Cleaning the System” underAdaptive
Cruise Control on page 3-20.
Flash-to-Pass
This feature allows you to use the high-beam
headlamps to signal the driver in front of you that
you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When you do, the following
will occur:
If the headlamps are off, in low-beam or in Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They’ll stay on as long as
you hold the lever there. Release the lever to
turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push
the lever away from you.
Windshield Wipers
The lever on the right side of the steering column
operates the windshield wipers.
7(Mist):Pull the lever down and release it for a
single wiping cycle. The lever will return to its original
position. For more cycles, hold the lever down before
releasing it.
9(Off):Put the lever in this position to turn off the
wipers.
&(Delay):Put the lever in this position to set a delay
between wipes. Turn the delay adjustment band to
set the length of the delay.
3-13

A single wipe will occur each time you turn the wiper
stalk to a higher sensitivity level to indicate that the
sensitivity level has been increased.
Notice:Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The mist and wash cycles operate as normal and are
not affected by the Rainsense™ function. The
Rainsense™ system can be overridden at any time by
manually turning the wiper band to low or high speed.
When Rainsense™ is active, the headlamps will turn on
automatically. The headlamps will turn off again once
the wipers turn off if it is light enough outside. If it
is dark, they will remain on. SeeWiper Activated
Headlamps on page 3-37.
Notice:Do not place stickers or other items on
the exterior glass surface directly in front of
the moisture sensor. Doing this could cause the
moisture sensor to malfunction.Windshield Washer
K(Washer Fluid):The lever on the right side of the
steering column also controls the windshield washer.
There is a button at the end of the lever. To spray
washer uid on the windshield, press the button and
hold it. The washer will spray until you release the
button. The wipers will continue to clear the window for
about six seconds after the button is released and
then stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
If the uid in the windshield washer uid reservoir is
low, the message CHECK WASHER FLUID will appear
on the Driver Information Center (DIC) display. It will
take 60 seconds after the bottle is relled for this
message to turn off. For information on the correct
washer uid mixture to use, seeWindshield Washer
Fluid on page 5-32andRecommended Fluids and
Lubricants on page 6-12.

If this symbol does not appear, or disappears briey,
Adaptive Cruise Control will not respond to vehicles
you may see ahead.
{CAUTION:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect
a vehicle ahead. Adaptive Cruise Control may
not have time to slow your vehicle enough to
avoid a collision. Do not use Adaptive Cruise
Control when the radar is blocked by snow,
ice, or dirt. Keep your radar clean. See
“Cleaning the System” later in this section.Adaptive Cruise Control will, automatically, slow your
vehicle down when approaching a slower moving
vehicle. It will then adjust your speed to follow the
vehicle in front at the selected follow distance. Your
speed will increase or decrease to follow the vehicle in
front of you but will not exceed the set speed. It
may apply limited braking, if necessary. When braking is
active, your brake lights will come on. It may feel or
sound different than if you were applying the brakes
yourself. This is normal.

Cleaning the System
The radar can become blocked by snow, ice or dirt.
If so, you may need to turn off the engine and clean the
lens. Remember, do not use Adaptive Cruise Control
in icy conditions, or when visibility is low, such as in fog,
rain or snow.
The emblem/lens is located in the center of the grille.
To clean the emblem/lens, wipe the surface with a
soft cloth. After cleaning the emblem/lens, engage the
Adaptive Cruise Control. If you are unable to do so, see
your dealer.
Headlamps
The exterior lamp control is located in the middle of the
turn signal/multifunction lever.
O(Exterior Lamp Control):Turn the control with this
symbol on it to operate the exterior lamps.The exterior lamp control has four positions:
O(On/Off):Turn the control to this position to turn off
all lamps and automatic lighting features including
Daytime Running Lamps and Intellibeam™
This is a “momentary” switch that will spring back to the
AUTO position when released. An AUTOMATIC
LIGHTS ON message will appear on the DIC when
automatic lights are enabled or an AUTOMATIC LIGHTS
OFF message will appear on the DIC when the
automatic lights are disabled.
AUTO (Automatic):Turn the control to this position to
put the headlamps in automatic mode. AUTO mode, if
enabled, will turn the exterior lamps on and off depending
upon how much light is available outside of the vehicle.
Due to the “momentary” switch design, your automatic
lights may be disabled even if you are in AUTO position.
To enable automatic lighting do any of the following:
Turn the headlamp control from AUTO to off
and release the switch. It will return back to
the AUTO position by itself.
Turn the headlamp control from the parking lamp
position to AUTO.
Turn the headlamp control from the headlamp
position to AUTO.

The other vehicle’s lamp(s) cannot be detected due
to dense exhaust, smoke, fog, snow, road spray,
mist or other airborne obstructions.
Your vehicle’s windshield is dirty, cracked or
obstructed by something that blocks the view of the
Intellibeam™ light sensor.
Your vehicle’s windshield is covered with ice, dirt,
haze or other obstructions.
Your vehicle is loaded such that the front end of the
vehicle points upward, causing the Intellibeam™
sensor to aim high and not detect headlamps
and taillamps.
You are driving on winding or hilly roads.
You may need to manually disable or cancel the
high-beam headlamps by turning the low-beam
headlamps on, if any of the above conditions exist.
Disabling and Resetting Intellibeam™
at the Rearview Mirror
Intellibeam™ can be disabled and reset to the original
factory setting by using the controls on the inside
rearview mirror.
O(On/Off):To disable the system, press and hold
this button on the inside rearview mirror for three
seconds and release it after the indicator on the inside
rearview mirror ashes two times. This lets you
know that Intellibeam™ has been turned off and will not
come back on until the system has been reset.
To reset the system, quickly press and release this
button on the inside rearview mirror. The indicator on the
inside rearview mirror will ash one time to indicate
that Intellibeam™ has been reset.
A different sensitivity setting is available for dealer
diagnostics. This is done by pushing and holding this
button for 20 seconds until the light ashes three times.
If you accidentally activate this, the vehicle’s setting
will automatically be reset each time the ignition
is turned off and then on again; otherwise, refer to the
text above for resetting the system.

SeeVehicle Personalization on page 2-47to select the
delay time that you want. You can also select no
delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on,
the exterior lamps will turn off about 10 minutes after the
ignition is turned off. This protects against draining
the battery in case you have accidentally left the
headlamps or parking lamps on. The battery saver does
not work if the headlamps are turned on after the
ignition is turned off.
If you need to leave the lamps on for more than
10 minutes, use the exterior lamp control to turn the
lamps back on.

Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the remote
keyless entry transmitter unlock button. If activated by
the transmitter, the lighting will remain active for
about 25 seconds. The entry lighting system uses the
light sensor; it must be dark outside in order for the
lamps to turn on. The lamps turn off about 25 seconds
after the last door is closed. They will dim to off if
the ignition is on, or immediately deactivate if the power
locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when the
key is in the ignition and the headlamps are on. This
feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness outside
and the parking lamps are active, the instrument
panel displays can be adjusted by turning the instrument
panel brightness knob. SeeInstrument Panel Brightness
on page 3-41for additional information.
Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on. Press it again to turn the lamp off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
a higher revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are on:
headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.

following:
1. Adjust the seat to a comfortable driving position. If
you change your seat position later, you may have
to re-adjust your HUD.
2. Start your engine and press the top or bottom of
the HUD button to center the HUD image in your
view.
The HUD image can only be adjusted up and down,
not side-to-side.
3. Turn the knob on the DIC control panel to adjust
the brightness of the HUD image.
The brightness of the HUD image is determined by the
light conditions in the direction your vehicle is facing
and where you have the HUD set. If you are facing a
dark object or a heavily shaded area, your HUD
may anticipate that you are entering a dark area and
may begin to dim.
To turn the HUD image off, turn the knob
counter-clockwise.

The rear window defogger will turn off about 10 minutes
after the button is pressed, or if the vehicle’s speed
is above 30 mph (48 km/h), the rear defogger will stay
on continuously. If turned on again, the defogger
will only run for about ve minutes before turning off.
The defogger can also be turned off by pressing
the button again or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when
the rear window defogger button is on.
Notice:Using a razor blade or sharp object to
clear the inside rear window may damage the rear
window defogger. Repairs would not be covered
by your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side or
up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.Turn the thumbwheel to the right to open the outlets
completely and allow the maximum amount of air
to enter your vehicle. Turn the thumbwheel to the left to
close the outlets and minimize the amount of air
entering the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-58.

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-35.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That is
normal.
If the ABS warning light comes on and stays on, there
may be a problem with the antilock portion of the
brake system. If the red BRAKE light is not on, you still
have brakes, but you do not have antilock brakes.
SeeBrake System Warning Light on page 3-64.
If the light stays on, turn the ignition to OFF/ACC. If the
light comes on when you are driving, stop as soon
as possible and turn the ignition off. Then start
the engine again to reset the system. If the light still
stays on, or comes on again while you are driving, your
vehicle needs service. If the regular brake system
warning light is not on, you still have brakes, but you do
not have anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
Brake System Warning Light on page 3-64.
